Ferrate Technology

For over 40 years, tens of thousands of publications have shown ferrate’s effectiveness in environmental applications. All of this research with subsequent pilot demonstrations has been performed utilizing small quantities of laboratory-synthesized ferrate compounds. Despite the astounding results observed with ferrate treatment of water, wastewater, sludge and industrial wastes, inexpensive, commercial sources of a ferrate compound have never been available in the market place.

Ferrate (FeO₄^2-) products are inherently unstable and cannot be stored or transported as with other commercial grade chemicals. These characteristics have precluded the ability of large chemical suppliers to produce commercial amounts of this chemical. In addition, previous attempts to commercialize this valuable commodity were unsuccessful due to the cost (> $100.00 per pound of FeO₄^2-) of producing a high-purity ferrate product. FS has developed proprietary blends of ferrate products that are now available at a commercial scale for < $5.00 per pound of FeO₄^2- .

After many years of research and experimentation in pilot studies, FS engineers have been able to design proprietary blends of inexpensive, commercially available feedstock chemicals, that when reacted together under proprietary conditions can produce a concentrated ferrate solution that is stable for weeks. This allows a workable solution of ferrate to be continuously generated nearby its point of use; either in remote locations, or central to several users of the compound.

In conjunction with our OEM, FS designs, fabricates, tests, installs, guarantees and maintains all components for site-specific designed Ferrate – based treatment systems. The FS Ferrate systems can be scaled to any size application. The unit operations of the systems are modular and easily transported to any location. These systems can be stand-alone, or interface with existing facilities. Total system design includes proprietary Ferrate synthesis, feed systems, flash mixing, flocculation, and clarification systems as required. Facilities for storage and handling of feedstock chemicals (ferric, caustic, and bleach) can also be designed and fabricated if the feedstocks are not already present at the site. All FS systems are fully process controlled and can be remotely controlled from central locations. FS engineers can interface their systems into any existing water, wastewater or industrial waste treatment system. FS treatment systems can be purchased outright or leased through one of several programs provided by FS.
